Revision History

Introduction

This chapter mainly introduces the overview and specification of the Tersus 2W Radio RS460H.

1.1 Overview

The Tersus 2W radio RS460H is a radio solution for both the base and the rover. It provides reliable data communications for mission-critical applications where a combination of stability, superior performance and long distance are required.

The RS460H is a lightweight, ruggedized UHF receiver designed for digital radio communications, which can be used widely in GNSS/RTK surveying and precise positioning system applications. The RS460H is equipped with a LED display and a keypad which is used for checking the operating status, changing the operating channel, and transmitting power level. It is easy to operate.

General Operation

2.1 Basic Operation

Figure 2.1 Front Panel of the Radio

Table 2 Definition for each button

The basic operations include:

  1. Boot up

The radio module is boot up directly when powered on.

  1. Channel switching

Press the channel switching button once, the channel is increased by one; the LED displays the current channel value; the channel display is 0 to 9, and the default is 0.

  1. Power switching

Press the power switching button once, the power is switched once; the power indicator is steady red to indicate high power 2W, and indicator is steady green to indicate low power 1W, and the default is high power.

  1. Protocol switching

The protocol button represents SATEL

  1. Transceiver mode switching

Simultaneously press and hold the channel switching button and power switching button for 1 second to switch the transceiver mode; T is steady red for transmit mode, and red light is flashing for transmitting data; R is steady green for receive mode, and green light is flashing for receiving data; the default is the receive mode.

  1. Restore default configuration

Simultaneously press and hold the power switching button and protocol switching button for 1 second to recover to the default configuration.

The LED definition is shown in the table below

Table 3 LED Definition

2.2 Software Configuration

The detailed steps of software configuration are as follows:

  1. Hardware connection
    Use the accessary cables listed in section 1.3 to connect the radio to the computer following the connection in the figure below. Power on the radio using 5V or 12V external power supply.

Figure 2.2 Hardware connection for software configuration

Table 4 Devices in Figure 2.2

  1. Radio Config Tool

Open the radio configuration software ‘TersusRadio Config Tool’ obtained from Tersus support. Ensure the port is selected correctly, then click [Connect].

  1. Read

After the connection is successful, click the [Read] button to read all the configuration information.

  1. Write

After the connection is successful, click the [Write] button to write all the configuration information. (Note: SN, PN, and firmware versions are read-only and cannot be written. Other parameters can be configured according to customer needs).

  1. Frequency Setting

Click the [Default] button to set all frequencies to the default values.

  1. Transmode Setting

If the box before [Reset to receive when reboot] is checked, the radio will be in the receiving mode after it is rebooted. Uncheck it, the radio will be in the transmit mode after it is rebooted. Remember to click [Write] to make this configuration effective.

Note: Transmode Setting function is only available for the firmware version V1.3.6 or later. Please upgrade radio firmware to use this function.

2.3 Firmware Upgrade

Use the accessary cables listed in section 1.3 to connect the radio to the computer following the connection in the figure below. Power on the radio using 5V or 12V external power supply.

Open the upgrade software ‘TersusRadioUpdate’ obtained from Tersus Support, select the corresponding port and firmware file, click [Next] and wait for the update to complete according to the progress bar.

2.4 Installation Tips

2.4.1 Radio installation

As a transmission, the radio is hooked on a tripod; as a rover station, the radio is installed in the rover station bracket.

(1) Large amount of heat would be generated when the radio is in transmission. When the radio is working, please do not place the radio in poor ventilated box, wrap or cover any item on the surface of the radio.
(2) In an environment with a high temperature of more than 40 °C or intense sunlight, the surface of the radio would be hot when it is transmitting at high power. It may cause scald if the surface of the machine is touched directly. Please pay special attention.

2.4.2 Antenna installation

Whether the antenna is properly installed and erected would seriously affect the transmission distance of the radio, hence the correct connection and installation of the antenna is of high importance.

(1) It is strictly forbidden to use a damaged antenna. The output impedance of the antenna interface of this radio is 50 ohms. Please use antennas and feeders with input impedance of 50±2 ohms and VSWR less than 1.5. Using an antenna that is not strictly matched with this radio would result in a shortened transmission distance for the radio, and it is possible to damage the radio if the mismatch is particularly serious.

(2) The original antenna of this radio is strictly matched with this radio, and the performance meets the requirements of this radio. The original antenna of this radio would better play the performance of this radio.

(3) Under normal circumstances, the height of the antenna installed from the ground would significantly increase the transmission distance and improve the transmission effect.

(4) Carefully check the connection of the antenna, feeder, connector and the components of the radio to ensure well contact and reliable connection between the antenna and the connector of the radio.
